    I just purchased Mountain Lion from the Mac App Store. The download went fine and I shut everything down and started the upgrade process.

    I got a message saying my computer was restarting, black screen, white screen with apple logo and chime, then.... Nothing. The screen is black and the light on the front is pulsing which tells me it's sleeping, not updating.

    Anything I can do or should I just leave it?

    That is not normal. Try to force a power down and restart. Start Disk Utility and do a verify disk to see if you have a bad drive maybe.
